I just deleted a post from a bot that posts the ridiculously long lists of hyperlinked random ASCII characters. I saw no way to ban him, although I managed to copy the IP address:
123.120.59.77
I realize that it is an untraceable bot, but how do I ban guests, if possible?

I'm thinking we are just going to disable guest posting, period.

Unfortunately, most spam-bots never use the same IP twice.
Any bans you can use would be useless.
Only thing we can do is delete them every time they pop up, and disable guest posting if we have to...

Alright...
I sure do wish I could send Blizzard Force (General Veers's squadron of elite AT-ATs at Hoth Echo Base) to eliminate all bots! I took care of three or so already in the glitches thread in Powder Game board.
I just remembered! That bot used the same IP several times.

Why not make the read-fuzzy-letters-then-transfer-to-box thing harder?
It might be reading them..

How can lines of code interpret images, which are not identified as text?
And do guests have to encounter the image-text test?

well we do have to face the fact that it might not be a bot at all it could be a regular person, copying and pasting huge posts like a bot would, chabging his ip everytime

and why would someone go to the trouble of doing that?

How can lines of code interpret images, which are not identified as text? And do guests have to encounter the image-text test? Some bots can read the letters in the image.(yes read, as in visually, not by analyzing any piece of coding) Heard it somewhere on wiki I think. Make the image harder to read, and the bot might not be able to "read" it. Guests will have to encounter it. But they're human, they wont have as much trouble.. EDIT: here, read. Actually, just skim, you should get the point.Forum spambots surf the web, looking for guestbooks, wikis, blogs, forums and any other web forms to submit spam links to the web forms it finds. These spambots often use OCR technology to bypass CAPTCHAs present. Some spam messages are targeted towards readers and can involve techniques of target marketing or even phishing, making it hard to tell real posts from the bot generated ones. Not all of the spam posts are meant for the readers; some spam messages are simply hyperlinks intended to boost search engine ranking. Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of images of handwritten, typewritten or printed text (usually captured by a scanner) into machine-editable text.OCR is a field of research in pattern recognition, artificial intelligence and machine vision. Though academic research in the field continues, the focus on OCR has shifted to implementation of proven techniques. Optical character recognition (using optical techniques such as mirrors and lenses) and digital character recognition (using scanners and computer algorithms) were originally considered separate fields. Because very few applications survive that use true optical techniques, the OCR term has now been broadened to include digital image processing as well. All in all, the bot might be using optical character recognition. We just need to make the characters less recognizable. Creativity might do it.

It isn't too hard for a program to decipher a simple CAPTCHA, it would just scan for patterns in the pixels that resemble letters. That is why many have lines and strange fonts, and sometimes random positioning.

interesting...
Is there a code to do that?

That is why many have lines and strange fonts, and sometimes random positioning. Yes, exactly what I was saying. Make the resemblance less... Or put something to make it less of a read and more of a decipher. Not so hard that it makes guest posting a pain, but maybe to confuse the bot.

Guest posting may be convenient, but that isn't always best. For instance, wouldn't it be so much easier for workers to get to their office if they had no doors? They wouldn't have to worry about forgetting their keys, just walk right in. Of course, so could anyone else who wanted their hard-earned cash. Think about it.

But the door has a lock, which is the CAPTCHA thingy... keeps out bad people from entering the office. But some bad people can pick the lock... I'm suggesting we improve the lock. All the good people will have keys, but the bad people will have to be that much smarter to pass through.

But the current CAPTCHA is provided by proboards; it is not an optional feature. It wouldn't be easy to change it.
